Review[Spondylodiscitis in kyphotic deformity of ankylosing spondylitis and its healing affected by dorsal correction osteotomies. Report of 33 patients].
Out of 144 patients with kyphotic deformities in Ankylosing spondylitis 33 (23%) had 45 disco-vertebral lesions of the spondylodiscitic type. They were characterized by osteolyses, scleroses and absence of syndesmophytes. 5 had additional arch fractures. All were localized in or below the apical vertebra in the lumber or the lower thoracic spine. ⋯ After a follow up of two years 98% were completely fused, also those with non-identical levels of correction and lesion. The loss of correction in the segments of lesion was negligibly more than in the total collective. 91% of the patients were pain-free compared to 12% preoperatively. The spondylodiscites were no hindrance for dorsal lordosing osteotomies and can be treated successfully by means of this static correction and the immobilisation.
